DETACHABLE' HANDLE FOR UMBRELLA-S.

Specification of Letters Patent.

Patented Aug. 8,1905.

Application filed September 13, 1904. Serial No. 224,271."

To all whmn it may concern:

Be it known that I, BENJAMIN ROTHSOHILD, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Detachable Handles for Umbrellas, of which the following is a specification.

This invention relates to umbrellas whose handles are separable from the rods.

The object of this invention is to provide an improved construction for this class of umbrellas whereby, first, the lengthof the umbrella may be shortened by removing the handle; second, the handle may be readily coupled with and uncoupled from the rod, and, third, when the umbrella is closed and the handle uncoupled and detached the mechanism contained wholly within the tubular rod will prevent the umbrella from being opened until after the handle has been attached.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a View, partly in section, of the handle detached from the rod. Fig. 2 is a side view of the upper end of the rod. Fig. 3 is a plan view of the end collar of the coupling secured on the rod. Fig. 4 is a plan view of one of thelocking-rings. Fig. 5 is a side view of the coupling-neck as seen when the locking-rings have been removed. Fig. 6 is a sectional View of the tubular rod and the means which will prevent the umbrella from being opened while the handle remains detached. Fig. 7 is a similar view of the tubular rod, showing the means for cutting out the device that prevents the umbrella from being opened. Fig. 8 is a detail View, separately, of the slidable check-block.

Referring to the drawings, the letter A designates the tubular umbrella-rod, B the handle, and O the coupling considered as a whole.

The rod A is tubular and at its end has two rigidly-secured collars or flanges (Z d, spaced apart and forming a neck a. The neck has a short slot f, and each collar secured to the neck has a notch f, which coincides with said slot f. The second collar 01, secured a short distance from the end of the rod, has a projecting finger or tang 7L.

A plural number of locking-rings g surround the neck and fill the space between the two collars (Z d. These rings are rotatable and cover the short slotf. Each locking-ring has a notch f on its inner circumferential edge corresponding to the notch of the rigid When the rings 9 have position on collars.

the neck 6, they may be turned so as to bring all the notches f 2 in register with the notches f and short slot f. In this position the notches and slot form a channel or groove that will permit the passage of thelateral pin k, presently to be described.

Each rotatable locking-ring has a short finger or tang h projecting from its outer rim. These serve to be grasped when it is desired to turn the rings. By placing the tangs h of the rotatable rings in position of coincidence with the tang h on one of the rigid collars it will be known that all the notches and the short slots are in register with each other.

The handle B, which may be of any preferred form or materialfor instance, woodhas a projecting metal shank e, which enters through the coupling collars and rings into the tubular rod A. This shank has an opposite endp", a collar j, rigidly secured around it, and a lateral pin it on the shank part, spaced apart from said collar a definite or predetermined distance Z. The end extends into the wood part of the handle, and the collar, 7' abuts snugly against the end of the said wood part, as seen in Fig. 1. It is thus easy to attach the grasp part of the handle to the metal coupling-shank, because the collar j serves as a guide or stop for the end of the handle and nov skill is required. It will be observed that the definite space Z between the rigid collar j and the lateral pin 76 is exactly suited to be filled by the thickness of the end collar cl and the several locking-rings g, whereby when the handle is locked to its position there will be no looseness of the handle.

The parts thus far described are operative as a coupling to secure the handle to the rod.

The ordinary runner m slides along the rod when opening or closing the umbrella, and when the umbrella is closed the ordinary spring-stop a, which projects out through a slot in the rod, holds the said runner and prevents the umbrella from opening.

The spring-stop has at its fixed end a lateral prong a, which takes in a hole punched in the wall of the tubular rod and is thereby held. On its convex-curved edge the spring stop-has a lug a Which bears on the inner wall of the tubular rod. This lug serves as a foot or fulcrum, and between the lug and the free end the stop is resilient.

The improved construction for preventing the umbrella from being opened while the handle is detached will now be described.

A spiral spring 0 is in the tubular rod and is held stationary therein by apin p. A suitable check-block q is arranged movably in the tubular rod A, so that when it has position immediately under the free end of the spring-stop n at the time the latter is normally out the spring-stop cannot be depressed, and of course the runner 77?. cannot be moved. This check-block q in the present instance is attached to a thin bar r, one end of which bears against the said spiralspring 0, and the other end, which is toward the coupling, has a suitable head r. This thin bar has a slot 8, through which the foot-lug n of the springstop sets. Thus the oar 0' may havean endwise-slidable movement without any interference of the foot-lug. The parts are so proportioned that when the spring 0 expands the check-block q will be under the free end of the spring-stop n, as seen in Fig. 6, and the head end-r of the bar will be at the most forward position toward the coupling. The parts will assume these positions when the handle B has been detached from the rod, and

as long as the handle remains detached the umbrella cannot be opened, because neither the spring-stop 11 nor the runner m can be moved. When in the present form of device the coupling-shank c' is inserted into the tubular rod, the end of the said shank impinges against the head 1" of the slidable bar. Then'when the shank is pushed in farther and the handle has been coupled the said slidable barf-rand the check-block q will have been moved back against the spring-pressure, and thereupon the spring-stop n will be free to be depressed to permit the runner m to be moved past'the spring-stop and open the umbrella. Thus the attachment of the handle has the effect to cut out from operation the means for preventing the umbrella from being opened.

The operation of coupling the handle'B to the rod A will be readily understood from the foregoing description.

I have heretofore shown, described, and claimed in United States Letters Patent No. 763,117, dated June 21, 1904, a detachable handle for umbrellas and acoupling for securing the handle to the rod, which coupling employs similar rotatable locking-rings to those herein shown. In the present case, however, the locking-rings are secured to the rod instead of the handle, as in the patent, one desirable result of which is that an umbrella made in the manner described in the present case will be much shorter when the handle has been removedthan is possible with the construction shown in the said patent.

Another advantage of the present construction as compared with that of the patent is that no metal socket is required for the wood handle and, further, there is an entire avoidance of any wedging of the lateral pin when the handle and rod are assembled or put together. Furthermore, by the present construction the tubular rod may contain means to prevent the umbrella from being opened while the handle remains detached.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an umbrella the combination of a tubular rod having at its end two rigidly-secured collars, d, d, each having an internal notch and the collars spaced apart forming between them a neck having a slot coincident with said notches; a plural number of notched rotatable locking-rings on said neck; and a handle having a projecting coupling-shank, 2', provided with a collar, 7', which contacts with the collar on the extreme end of the said rod and also provided with a lateral pin, 70, which is spaced from said collar a distance equaling the combined thickness of one of said end collars and all the locking-rings.

2. In an umbrella the combination of a tubular rod having at its end two rigidly-secured collars each having a notch and the collars spaced apart forming between them a neck and one collar having a projecting finger or tang, la; a plural number of locking-rings loose on said neck and each ring having a finger or tang, h, projecting from its rim; and a handle having a coupling-shank which is provided with a lateral pin, in.

3. In an umbrella the combination of a tubular rod, A; a runner, on, movable on the said rod; a spring-stop, n, which projects from the rod to hold the said runner from moving when the umbrella is closed, and is depressed to allow the umbrella to be opened; a checkblock, q, slidable within the tubular rod so that when in the forward position it will prevent the said spring-stop from being depressed and said check-block having a head,- 1", extended toward the handle end of the rod;

a spring, 0, which normally presses said check block forward; a removable handle, B, having a coupling-shank, 2?, which enters said tubular rod and whose end impinges against said extended head and slides the check-block to its backward position, and a coupling for fastening the said handle to the rod.

In testimony whereof I affix my signature in presence of two witnesses.

BENJAMIN ROTHSGHILD.
